Hardware and Performance / question about multi-wan-performance
« on: February 25, 2021, 02:26:24 pm »
hello @all.
i am running an opnsense OPNsense 21.1.2-amd64 on an Intel(R) Atom(TM) CPU C3758 @ 2.20GHz (8 cores).
Due to my poor VDSL connection (110Mbit down & 40 Mbit up) i have added 2 LTE Router (Huawei) (each ~ 70-90Mbit down & 20-40 Mbit up) in NAT-behind-NAT setup. The firewall has disabled sticky connection and is on aggressive mode.
Also i did follow the howto of setting the loadbalancing up and made them all the same weight and tier.
When i connect (use) each WAN 1, WAN2 or WAN3 in single setup i get full speed. This i can verify by connecting a WiFi device to the huawei routers and do an speedtest.
All connections by itselt are workoing correctly.
When i use the GW-Group as my Gateway, then it is also working, however the combined speed is at most 210Mbit, while the upload is up to 120Mbit.
So if i calculate for upload 40+40+40Mbit = 120Mbit for upstream the GW-Group works fine.
However, when i download, i only get max 210 Mbit (usually less), which isn't 110 + 80 + 80 Mbit = 270 MBit (or more).
The CPU load is with traffic between 20-40%.
Is this normal behavior? What can i do to improve the combined download so that i actually can reach the real limits?
Thank you in advance.
